When I was 16 years old, I opened the door of the bathroom to use the toilet for a pee. The toilet is in another cubicle accessed via the bathroom. I didn't know that dad was having a bath. I passed by him and pretended not to look at him. He was laying on his back. He had a very full hard on and his foreskin was fully pulled open. He had smeared a thick coating of soap on his knob. I realised that the soap was to act as a lubricant when he would run his hand up and down his cock. I left the bathroom and closed the door, still pretending I hadn't noticed anything. A short time later, I heard a rhythmic splosh, splosh sound coming from the bathroom. Now I knew what he was doing! Dad was normally a very conservative guy and I quickly learnt never to even hint at anything sexual, or he would get very angry, but here was the same guy heart and soul into a wonderful masturbation session. People back then were such hypocrites! Many years later, I drove to our holiday house, about an hour from home. I didn't know that dad was there, not that that should have mattered anyway. He used to go there on his own from time to time to do some fishing. There is a long winding path up to the holiday house in the bush. I got partway up the path, when I saw dad come out of the house. He was completely in the nude except for his sand shoes. He had a very large erection and was briskly stroking it up and down as he walked. I kept out of sight. He walked around the house to the basement. At one stage, there was no power supply to the house and there used to be a small power generator in the basement with its exhaust pipe sticking out through the wall of the house. This was long gone and only the hole in the wall remained. This hole was about one and a half inches in diameter. Dad walked up to this spot and poked his cock into the hole, then began fucking it. I was stunned! He continued with his cock stimulating massage for about 7 minutes, then let out a loud OH!OH! AHHH! Obviously he was experiencing a profoundly intense wonderful orgasm. He continued fucking the hole for about another minute before withdrawing his cock. When he did, I could see the sun glinting off his shiny wet knob. His cock was pulsing up and down. Now he slowly hand stroked his still stiff cock for about a minute. What a happy man! I quietly crept away and drove off. Next weekend, I went back to the holiday house. This time, dad wasn't there. I unlocked the basement door and went in. I wanted to check the inside wall where the hole was. I was going to count the number of yellowed dribbled stains on the inside of the wall, however, there were too many to count! I found out much later in life, that mum had lost all interest in sex early in their marriage, so dad obviously had to do something about it. I was thrilled that dad loved sex so much and masturbation in particular. Has anyone else tried fucking a hole in a wall, or knot hole in a fence?
Not me. My wife still does everything I need. Not out of duty, but love. If I had to satisfy myself in other ways, Rosy Palms would be on my call list. Maybe a fleshlight. But a knot hole? No way! Too many splinters!
